When i highlight the cells and press delete cells it asks if i want to delete the whole row.
IMHO that message is not from Excel itself, looks like a message box from a macro running in the background.
Please follow these steps:
Close Excel
Press and hold the CTRL key
Open Excel
Wait for a message to appear and ask for "Safe Mode"
Release the CTRL key
Click Yes
After Excel opens
Click File\Open and select your file
Press and hold the SHIFT key
Click Open
Wait for your file to open
Release the SHIFT key
Test the behavior
Does the same message pop up if you try to delete the same cells?
